Question

我正在尝试通过制作一个简单的披萨订购系统来熟悉PHP，该系统通过电子邮件发送大小，配料和订购者的信息。电子邮件很好地发送，但电子邮件的顶部部分是空白的。我错过了什么？

谢谢！

Answer 1

替换文本域名称之间的所有空格，例如：使用halfonions而不是使用带有Half Onions

空格的textname

if(isset($_POST['halfonions']) &&   $_POST['halfonions'] == 'Yes') {

而不是

if(isset($_POST['Half Onions']) &&   $_POST['halfonions'] == 'Yes') {

Answer 2

你没有设置你的变量，你只是回应它们：

/* the following code is currently not working */
$pepperoni = $_POST['pepperoni'];


if(isset($_POST['pepperoni']) && 
   $_POST['Pepperoni'] == 'Yes') 
{
    echo "pepperoni";
}
else
{
    echo "";
}

现在$pepperoni变量将包含Yes（如果已选中），而不包含任何内容。这是您当前尝试设置的唯一变量，消息中的其余变量未定义。

您可能需要以下内容：

if(isset($_POST['pepperoni']) && 
   $_POST['pepperoni'] == 'Yes') 
{
    $pepperoni = "pepperoni";
}
else
{
    $pepperoni = "";
}

对于您在邮件中使用的所有变量。

你可以将其减少到：

$pepperoni = isset($_POST['pepperoni']) ? 'pepperoni' : '';
                           ^ or however it is spelled in the html...

因为价值并不重要。

Answer 3

我认为变量中有空格，如“半意大利辣味香肠”或“半蘑菇”!!

PHP复选框不会在电子邮件中发送是/否值
